Basic tools like SMS messenger crashed all the time and I reformatted several times within just months of having it.
Interesting. My X10 mini has never had any kind of bug in SMS system or anything else.
To be honest, only 1 problem rarely happens: an application stops responding and the OS tells that to me, asking if I want to force close it.
I've NEVER had any bug or problem with SMS system, either using original app or 3rd party (downloaded from Android Market) apps.
I don't know if your EVO just sucks, if it came broken or if you're just another troll saying as many ******** as you can.
Your particular problem doesn't represent the whole Android scene.
If Android is that garbage that you talk about, it wouldn't get the same market share that iOS already has.
